Abstract:
A metal cutting band saw is provided that includes a main carrier, on which an intermediate carrier is pivotally mounted. The saw frame, which can be adjusted in the direction of the workpiece, is mounted on the intermediate carrier by means of a swivel support or a parallel guide. The swivel support for connecting the main carrier to the intermediate carrier is located above the workpiece to be processed.
Abstract:
There is disclosed a sawing machine including a workbench, a band saw pivotally installed on the workbench, a weight movable between an idle position on the workbench and an operative position on the band saw and an adjustable torque provider for providing an adjustable torque to the band saw. The adjustable torque is set to a maximum when the weight is in the idle position in order to lift the band saw from the workbench. The adjustable torque is set to a minimum when the weight is in the working in order to lower the band saw toward the workbench.

Abstract:
A vertical band saw machine in which a carriage assembly is mounted for pivoting on a base by rotational pivot points. Pivoting of the carriage assembly enables the band saw machine to make miter cuts to a workpiece. The head frame of the band saw machine travels on a guide on the carriage assembly and moves only in the direction of the plane of cut. A vise assembly is preferably attached to the carriage assembly and pivots with the carriage assembly for keeping the vise assembly close to the line of cut at all times, regardless of carriage assembly orientation. A driving wheel and driven wheel are attached to the head frame and may be tilted with respect to the head frame.
Abstract:
A mechanical hand for processing edges of a curved plate is attached to the hand supporting member of a robot arm and in use is moved along the edges of the curved plate, which is made of glass, ceramics, metal or the like. The mechanical hand has a fixed bracket fixed to the hand supporting member; a movable bracket supported by the fixed bracket so as to be capable of tilting around a point of processing which is determined to be on the axial line of the robot arm and which corresponds to part of the edges of the curved plate; a processing tool mounted on the movable bracket to face the part of the edges of the curved plate at the point of processing; and a driving means for causing the movable bracket to tilt so that the posture of the processing tool coincides with a surface of the edges to be processed of the curved plate at the point of processing.
Abstract:
A horizontal bandsaw has a main vise positioned slightly to the rear of the cutting location for gripping the workpiece during cutting, a material feed vise positioned to the rear of the main vise for feeding material into the cutting location, and a front vise positioned to the front of the cutting location. The front vise can move to a position to the rear of the cutting location to retrieve a small remnant of uncut material. The three vises each have a movable and a fixed jaw. A lower limit guide is provided on the main vise movable jaw which adjusts the descent of the cutting tool to the width of the workpiece. The fixed jaws are provided with means located within the operating area of the jaws for a slight advance or retraction of the contact face, to firmly grip the workpiece or to retract the contact face so as to prevent frictional contact with the workpiece. The movable jaws have a hydraulic cylinder built into a sliding tube for providing reciprocating motion. A moving position detection device is mounted on the material feed vise for determining the extent of longitudinal motion of the material feed vise so that the material feed vise can be positioned at a presecribed position. A laser beam head is mounted on the cutting head to verify accuracy of positioning of the workpiece. A rotating brush device has an easy mounting and dismounting construction.
